Question

我有一个Web解决方案，里面有一个WCF服务项目。我们需要支持“无cookie”。所以在web.config中，它被设置为

 <sessionState 
    mode="SQLServer"
    sqlConnectionString="Data Source=ds;Initial Catalog=db;User Id=uid;Password=pwd" 
    allowCustomSqlDatabase="true" 
    cookieless="true" 
    timeout="720" 
    regenerateExpiredSessionId="false"/>

WCF服务将支持会话，因此我们还在web.config中将“aspNetCompatibilityEnabled”设置为true。

<serviceHostingEnvironment aspNetCompatibilityEnabled="true" 
                           multipleSiteBindingsEnabled="true"/>

服务和接口如下，

[ServiceContract(SessionMode=SessionMode.Allowed)]
public interface ICDOCService
{ }

[AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)]
public class CDOCService : ICDOCService
{ }

我们面临的问题是我们无法从任何客户端应用程序访问该服务。（Web应用程序，WCF测试客户端）

当我们通过WCF测试客户端访问

时，会显示以下错误

无法调用该服务。可能的原因：服务离线或无法访问;客户端配置与代理不匹配;现有代理无效。有关更多详细信息，请参阅堆栈跟踪。您可以尝试通过启动新代理，还原到默认配置或刷新服务来恢复。

内容类型text/html;响应消息的charset=UTF-8与绑定的内容类型（multipart / related; type =“application / xop + xml”）不匹配。如果使用自定义编码器，请确保正确实施IsContentTypeSupported方法。响应的前1024个字节是：

根据@Jeroen的建议重新发表我的评论，因为它似乎有助于OP。

听起来你有相互排斥的要求。如果你绝对不能使用cookies，还有其他方法可以在不使用Session的情况下访问所需的信息吗？也许是持久性数据存储（如数据库中的表）？

WCF服务没有被调用
